How to Tone Oblique Muscles Without Weights

When doing an abdominal workout it's important to work all ab muscles, which include the lower and upper abdominal muscles and the obliques. The oblique muscles are the abdominal muscles that run diagonally on the sides of the stomach. Although it is impossible to spot reduce, you can tone your oblique muscles and give your waistline a tapered appearance. Working your oblique muscles can be done anywhere without even using weights.

Perform oblique crunches. Lie on your back and bend your knees. Keep your feet together and allow your legs to fall to one side of your body. Keep your knees together, place your hands behind your neck and raise your shoulders about 6 inches off the ground into a crunch position. Lower your shoulders back down slowly. Repeat on both sides.

Do truck twists. Place your feet shoulder width apart and place your hands on your hips. Twist only your upper body as far right as you can. Rotate back to the front and twist left.
